The Circle of Willis — Nature’s Brain Backup System
Deep at the base of your brain lies a remarkable ring-shaped network of arteries called the Circle of Willis. Think of it as a built-in emergency power supply for your brain.
It connects the major blood vessels from the neck (the carotid and vertebral arteries) & distributes blood evenly to both sides of the brain.
Why is it so important?
Bcos when one artery gets blocked, this circular design allows blood to reroute through other pathways — protecting ur brain from sudden damage.
But when it fails…
A weak point in this circle can balloon & rupture, causing a brain aneurysm or stroke.
That’s why high blood pressure, smoking, & uncontrolled cholesterol are dangerous , they weaken these vessels.
It's important to know that:
Your brain depends on a constant, uninterrupted blood supply. Treat ur blood vessels well — ur Circle of Willis is working behind the scenes every second to keep you alive.
